Abstract: Adversity stresses such as drought, salinity and pest etc. have become the main factors restraining plant growth and crop productivity. Plants have evolved a series of mechanisms from morphology to physiology for alleviating stress-causing damages. Accumulated aldehydes may generate peroxidation chain reaction and then damage normal physiological function of cell membrane system. Excessive aldehydes may also react with proteins and nucleic acids and destroy their normal structures and functions, even directly cause the plant death. The expression of the plant aldehyde dehydrogenase gene(ALDH)can be increased by stress induction, and a large number of accumulated aldehyde dehydrogenase proteins(ALDHs)oxidize aldehydes into corresponding carboxylic acids, therefore this reduces the peroxidation of lipid, and involves in stress adaptation on biotic and abiotic environments and plant developmental regulation. This review will summarize the classification, function and pathway of plant ALDHs in detail.

Key words: plant aldehyde dehydrogenase, adversity stress, research progress
